Which component provides a visible indication of air leak patterns and trends?

• A. The graduated air leak monitor
• B. The suction regulator dial
• C. The drain collection chamber
• D. The vent filter

Answer: (A)

In chest tube systems, watching for air leaks helps you judge whether the tube and lung are functioning properly over time. The graduated air leak monitor is designed to give a visible readout of how much air is leaking and how that leak changes, usually through bubbles or a calibrated scale. This lets you see trends at a glance—whether the leak is increasing, decreasing, or staying the same—which informs decisions about suction, tube position, or need for intervention. The suction regulator dial sets how strong the suction is but doesn’t show leak patterns. The drain collection chamber mainly tracks drainage volume, not leak trends. The vent filter simply vents air to atmosphere and doesn’t provide a readout of leaks.
